In this talk, Nick Bostrom discusses the concept of crucial considerations and how we can use it to maximize our impact on the long-term future.

"So I want to talk about this concept of a crucial consideration, which comes up in the work that we’re doing a lot.

You’re carrying some weight, maybe you have a lot of water because you need to hydrate yourself to reach your goal and carry weight, and trying to fine-tune the exact direction you’re going. You’re trying to figure out how much water you can pour out, to lighten your load without having too little to reach your destination."
